Official Description

Radiation treatment delivery, 2 separate treatment areas, 3 or more ports on a single treatment area, use of multiple blocks; 6-10 MeV

Common Language Description

The CPT® Code 77408 refers to the process of delivering radiation treatment to a patient, specifically targeting two separate treatment areas using three or more ports within a single treatment area. This procedure is designed to effectively administer radiation therapy aimed at destroying tumors or cancerous cells. The term "ports" in this context refers to the specific entry points through which the radiation beams are directed into the body. The procedure utilizes a radiation beam strength classified as 6-10 megavolts (MeV), which is a measure of the energy of the radiation being used. This energy level is crucial as it determines the depth of penetration and the effectiveness of the treatment in reaching the targeted tissues. It is important to note that if a higher energy beam is used, such as 11-19 MeV or 20 MeV or higher, different CPT codes (77409 and 77411, respectively) would be applicable. The use of multiple blocks during the treatment is also a key component, as these blocks help shape and direct the radiation beams to optimize the treatment while minimizing exposure to surrounding healthy tissues.
